Radiant:

binds...
	* ctrl + shift + m1 (in texbro): open shader in external editor
misc...
	* fix: do not unmaximize external shader editor on win
	* fix: blank cursor in radiant after calling external shader editor on win
	* fix shader editors stuff for non uindowses
	* 'Shader Editor Command' preference is available on win (is used, if set; otherwise try default os action for file)
	* fix: 'Shader Editor Command' preference allows selecting executable via dialog
	* GDK_HAND2 cursor in clipper tool mode
	* fix: clipper points have numeric labels
	* '2d zoom in to mouse pointer' option works for alt + m2 zoom
	* '3d zoom in to mouse pointer' option (def = yes)
